hasNext

public boolean hasNext()

Description copied from interface: IQuery

Indicates of there is a hit available.

Specified by:

hasNext in interface IQuery

Specified by:

hasNext in interface Iterator<QueryResult>

Returns:

True if a hit is available, false if not.

next

public QueryResult next()

Description copied from interface: IQuery

Gets the next hit for the last query.

Specified by:

next in interface IQuery

Specified by:

next in interface Iterator<QueryResult>

Returns:

A QueryResult object that holds the source and target text of the hit, or null if there is no more hit.

clearAttributes

public void clearAttributes()

Description copied from interface: IQuery

Removes all attributes from this query engine.

Specified by:

clearAttributes in interface IQuery

removeAttribute

public void removeAttribute(String name)

Description copied from interface: IQuery

Removes a given attribute from this query engine.

Specified by:

removeAttribute in interface IQuery

Parameters:

name - The name of the attribute to remove.

setAttribute

public void setAttribute(String name,
                         String value)

Description copied from interface: IQuery

Sets an attribute for this query engine.

Specified by:

setAttribute in interface IQuery

Parameters:

name - name of the attribute.

value - Value of the attribute.

setRootDirectory

public void setRootDirectory(String rootDir)

Description copied from interface: IQuery

Sets the root directory that may be used to replace the available ${rootDir} in the parameters of this object.

Specified by:

setRootDirectory in interface IQuery

Parameters:

rootDir - the root directory.

getParameters

public IParameters getParameters()

Description copied from interface: IQuery

Gets the current parameters of this connector.

Specified by:

getParameters in interface IQuery

Returns:

the current parameters of this connector or null if no parameters are used.

setParameters

public void setParameters(IParameters params)

Description copied from interface: IQuery

Sets the parameters for opening and querying this connector.

Specified by:

setParameters in interface IQuery

batchQueryText

public List<List<QueryResult>> batchQueryText(List<String> plainTexts)

Description copied from interface: IQuery

Starts a batch query for a given list of plain texts.
Note that batchQueryText does not use hasNext and next methods. Callers must use the returned list directly.

Specified by:

Returns:

a list of lists of query result. Each list corresponds to a source text (in the same order)

leverage

If the entry to leverage has already one candidate with a score equals or above this value, no query is performed. Use 101 to always allow the query.

Specified by:

setNoQueryThreshold in interface IQuery

Parameters:

noQueryThreshold - no-query threshold (a value between 0 and 101).

getNoQueryThreshold

public int getNoQueryThreshold()

Description copied from interface: IQuery

Gets the threshold for when to avoid a query.

Specified by:

getNoQueryThreshold in interface IQuery

Returns:

the current no-query threshold.
